Application January 13, 1933. Serial No. 651,596

3 Claims. (01. 139-295) I My invention broadly relates to improving thecloth tensioning function of the Dutcher type loom temple as exemplifiedin the Dutcher, Reissue Patent No. 6,831 or the Stimpson Patent No.M31288. Due'to the fact that temples of this class generally have apredetermined and fixed cloth receiving space between the cap and theroll or rolls, it has been found that cloths of greater thickness have agreater frictional engagement than those of thin construction with theresult that it was necessary to change the entire temple or at leastsubstitute rolls of different surface characteristics when the loom waschanged from weaving one class of goods to another. My temple because ofthe inclusion in the cap construction of a vertically adjustable clothtensioning bar enables any set of temples to be used in the weaving ofgoods of great variety with merely adjustment of the said tensioningbar.

Furthermore it has been found possible to eliminate the marking of lightfragile goods as silk or rayon by the toothed rolls which it was foundnecessary to use in the old style temples to secure the proper lateralcloth tension.

In temples of the prior art it has been found that after continued usethe cloth engaging rolls were worn so that they had to be renewed forproper lateral stretching of the cloth. With the use of the adjustabletensioning bar of my invention it is possible to continue in operationany one set of rolls from one quarter to one third.

longer than with the known temple caps.

In the accompanying drawing,

Figure l is a plan view of the temple head of my improved device.

Figure 2 is a cross-section taken on the line 2-2 of Figure 1.

Figure 3 is a cross-section on line 3-3 of Figure 1, but showing awarpwise section of the cloth as it moves through the temple.

Figure 4 is a side view of the temple cap showing in dotted lines thegroove for receiving the cloth tensioning bar and the screw holesthrough which the adjusting screws are passed. I

The specific elements of the device as illustrated in the drawing andbearing corresponding reference numbers, are as follows: The usual rspring pressed supporting bar is numbered 1 and carries the base 2containing the cloth engaging rollers 3 rotatively mounted in bearingsin said base. The cap 4 is securely fastened to the base 2 by a screw 10at a sufilcient distance to permit cloth of the maximum thickness topass freely between the two as clearly shown in Figure 3.

In the prior art devices this space was in effect variable only withinnarrow limits by means of washers or packing between the shank of thecap and the base or by filing the cloth engaging edges of the cap, bothwith bad results in varying the tortuous path of the cloth anddiminishing the wrapping of the cloth about the rolls.

As clearly shown in Figures 2 and 3 the cloth tensioning bar 6, which isapproximately the same length as the rolls 3, is slidingly mounted in arecess in the central ridge 5 of the cap 4 in parallel relation to thecloth rolls 3 and, if two such are used as in the illustrated example,vertically above the intervening space. The screws 7, 6 are threaded inthe cap ridge 5 and their ends determine the uppermost position of thetop of bar 6 while the screws 9 pass freely through the ridge and arethreaded in the bar. By turning the screws 9 either right or left thebar 5 may be raised or lowered so as to place the edge 8 in properrelation to the cloth as shown in Figure 3. Once the proper position ofthe bar has been determined it can be securely locked by turning downthe screws 7 into firm engagement with the top of the bar.

As clearly shown in Figure 3 the tapered edge portion 8 of thetensioning bar bears directly on the cloth and forces it to follow atortuous course underneath the edges of the temple cap, over the rollsand under the edge of the bar. Theextent of the bending of the cloth andwrapping thereof about the upper surfaces of the rolls is determinableby the vertical position of the bar 6 and in view of the ease ofadjustment it is possible to locate the bar at the required height forfirmly and correctly tensioning cloth of any weight or texture. I

Inasmuch as the proper tensioning of the cloth as woven is an importantand essential element of good weaving, my invention in its results offull and correct lateral tensioning of cloth of any quality and at alltimes is a substantial improvement over the prior art. As there are manypossible changes of elements of my device as illustrated,'f0r example inusing one or three rolls instead of two or varying their position whichare within the scope of my invention I wish it to be limited only by theterms of the appended claims.

I claim:

1; In a loom temple the combination of a base, rolls rotativelysupported thereby, a cap having a recess extending longitudinally forthe greater part of the length thereof, a bar having a straight narIOWcloth-engaging edge normally fixed in said recess but adapted to beadjusted vertically to different positions therein so as to vary thetortuous course of the cloth between the rolls and the lower edge of thebar.

2. A loom temple having rotatable lower rolls and a longitudinallyrecessed cap in combination with an upper cloth engaging bar tapered toa straight, smooth lower edge, said bar adapted to be verticallyadjusted in the cap recess so that the lower edge thereof may be fixedfor operation in any desired position in the middle vertical planebetween the rotatable rolls and below the plane tangent to the uppersurfaces of both rolls for the purpose of determining the sinuosity ofthe cloth selvage passing between the rolls and the bar.

3. A loom temple head having, a base and cloth engaging rolls rotatablysupported thereon in combination with a cap fixed to the base, anenlarged central ridge portion on said cap containing a rectangularrecess extending in parallelism with said rolls, and a cloth engagingbar having a substantially rectangular body portion slidingly mounted insaid recess so as to be vertically movable, said bar having a lowertapered cloth engaging portion, and means to vary the vertical positionof the bar so as to locate the cloth engaging edge of the taperedportion between the rolls and below the plane tangent to their uppersurfaces thus in operation serving to bend the passing cloth about therolls to a greater or lesser degree to vary the frictional engagement ofthe cloth with the rolls and thereby provide correct lateral clothtensioning.
